This invention relates to the production of coated paper bearing visible ornamentatlon or designs or words, andhas particular reference, although not limited thereto, to

waxed paper 0 the kind-employed for bread wrappers.

When coated paper is employed for wrapping irregular or somewhat soft articles such as loaves of bread or cake, the operation of l wrapping and the subsequent handling causes moreor lessawrinkling of the paper which is visibly emphasized in the coating and is unsightly. When the coating is of a waxy nature, such as parafline, wrinkles or creases show whiter than the rest of the'area of the paper, this being due to the cracking ,illustrated by the accompanying samples, the

of the wax, converting its smooth continuity .into very small particles. 7

One of the objects of my invention is to 2 utilize this characteristic of the coating-to save the expense-of the ink usually employed for printing the paper to ornament or cause .it to indicate its origin, and to save the time required to effect such printing. Heretofore it has been customary, when 1t is desired to ornament the paper or identify the goods enclosed in waxed paper wrappers by symbols or designs, words or names, to first print the paper while in the web, and then coat the ink-printed paper with parafline.

I attain the above mentioned object by first coating the paper and then impressing the symbols or othervisible matter directly ink or other coloring matter. ThlS, when the coating" is parafiine, results in all of the lines which form the symbols, designs, words or names, showing what maybe properly described as a fro 'white because of the crushin effect of t e impressions. Anot er object of my invention is to counteract or camouflage the appearance of cracks or creases which may appear as the result of wrap ing' or handlin I attain this objectuby' orming or provi lin in the coating, suchdesigns or symbols or words or names as will have the same appearance (ex- 7 cept as to shape) as cracks or creases, there; 50 by rendering such cracks or creases less noticeable.

With the above mentioned objects in view, invention consists in the sheet material,

in the coating without employing printing and the method of-producing the same, sub-.

opposing and web-supporting roll or cylin- -der may wellbe of uncovered steel. And

the paper but only-the coating. Therefore suitable rotary printing press which latter stantially as hereinafter described and claimed.

The drawing illustrates a piece of waxed paper bearin onesuitable kind of design produced in t e manner described herein. In carrying out my present invention as paper, after being coated by a machlne such as illustrated in Letters Patent No. 1,1 10,- 87 3, granted tome May 25, 1915, or by any other suitable waxing machine, is sub ected to the pressing action of what may be. re- -ferred to as printing plates or type-although.

-no print e1"s ink or other coloring substance isemployed, which pressing action simply crashes the coating: Said lites 'or'ty emay be a part of any preferre printing mechanism. In other words, any printing ress may be employed, but with the ink-app yi-ng parts thereof removed or rendered inactive. The web of paper may pass directl fromilo such a'machine as illustrated in'the' tters. Patent above referred to, to such printing press, or it may be acted upon later to effect the marking of the coating. In any case, it is preferable that the aper, during the action of the pressing p ates'or type, shall be supported by an unyielding surface. For instance, if the pressing plates or ty es are carried by a "revolving roll or cylin er, the

the adjustment of the couple viz: the 00- operating roll or cylinders, will be such that the pressing plates or types will not affect the paper itself isnot weakened in an way due to the impression of the design in thecoating.

Anexpeditious method of practicing the invention is to lead the paper, in the form of a web, from such a wa m e as i1-' lustrated in the Letters Patent hereinbefore vreferred to, and cause it to continue to travel directly between the printing couple of a has no operative ink-supplyin parts. The

coating, of course, is hardene as-it leaves the waxing machine.

To obtaln the best results, when the paper is heavily coated with wax, the adjustment of the printing couple is 'such as to effect somewhat greater pressure than is employed for ordinary printing of uncoated paper with ink. This is for the purpose of converting the smooth surface of the wax into .for the purpose of identifyin its origin or the'goods to be wrapped therein, whether the printing is purely a matter of ornamental design or consists of words or names,'i t is to be understood that in practicing my invention the identifyin characters may be purely ornamental orfiescriptive by means of words or names or anything capable of being impressed in the coating by plates or types or any equivalent thereof.

Designs produced in the manner described difier materially from the efiect of making impressions on waxed paper by means of heated dies or other implements, because in heating at a sufiicient temperature to afiect the waxed coating, instead of leaving any broken portions of the wax to cause a frosty appearance, it simply leaves an impression having a shiny surface and rendering the paper as a whole more transparent than the areas surrounding the. design or impression.

Having. now described my .invention, 1'

claim 1. Paper having a coating of wax having crushed portions to provide identifying characters'in said coating. I

2. .Bread wrapping material comprising aper having a coating of; wax bearing osty white identifying characters consisting solely of crushed particles of wax.

3. 'The method of producing wrapping with wax-crushing pressurefiagainst the coating.

In testimony whereof llhave afiixed my signature.
